Applleatlon filed May 20i 1907. Serial No. 374.688.

To all whom it may concern:

Be it known that I, Sansa E. an'rnaia., a citizen of the United States, residing at Athens, in the county of Menard and State of Illinois, have invented a certain new and useful Combined Cutter and Basler, of which the following is suoli a full, clear, and exact description as will enable others skilled in the art to which it appertains to make and use my said invention.

The purposes of this invention are to provide in connection with shears, sewing mechanism operative by the shears, to sew loosely together or baste the fabrics cut by the shears; to provide stitch-forming mechanism of improved construction and to provide simple and effective means for connecting the sewing mechanism with the shears.

With these ends in View my invention consists in the novel features of construction and combinations of parts shown in the annexed drawings to which reference is hereby made and hereinafter. particularly described and finally recited in the claim.

in the drawings similar reference letters and numerals designate like parts in the several views.

Figures 1, 2. and 3 are res iectively a side elevation, a top lanand a )ottoni plan of the ap aratus. i ig. 4 is an enlarged top view o the looper, showing the position of the looper jaws relative to the needle at the instant before the looper enters the loop. Fig. 5 is an enlarged to i view of the looper showing the osition o the 'aws relative to the needle w ien the needle llias moved )art wav downward between the jaws and the shoulders of the jaws have engaged the loop suhstiintiall as shown in Fig. l2, also showing in dotted lilies the position of the jaws relative to the needle at lthe instant preceding the withdrawal of the jaws from the needle; Fig. (i is an enlarged side elevation of the looper; Fig. 7 is an enlarged partial vertical section on the line 7. 7. of Fig. .2 and shows the means for connecting the needle with one blade of the shears; Fig. 8 is a pers iective view of the presser plate detached; l* ig. J is a erspective view of the table detached and Figs. l0 to l5 inclusive, are diagrams illustrating the forming of the loop and the stitch at different stages of the operatoii. ln some of these views the table 3 and the presserilate 2 are shown as abnormally so )arated irom each other in order to more clearil y illustrate the fabrics, and the thread situated between the plates.

The shear blades l and 1 are of the usual forni and are connected by a pivot l". l`he blades l and l are respectively provided with studs l which may be integral with the blades or may be made se )arately and secured thereon by any suitalile means.

'l`he presser plate 2 is firmly secured on theI blade l and extends lengthwise parallel to the blade, the iniiel edge. of the plate being away from the blade l" a distance sullicieiit to permit the cutting edge. of the blade l to enter th(` space between the presser-plate 2 and the blade. l. 'l"he plate .2 has a laterallyr project-ing lug .Z, pierced by holes 2". Screws '.2 extend through the holes 2" and screw into corresponding holes in the upper part of thc bliide l, and secure the plate .2 on the blade l. 'l`he presser plate bears upon the fabrics on the table 3 when the shears are closed and serves to keep the fabrics smooth during the cutting and prevents tangling of the thread during the operation of basting.

A table 3 is firmly secured on the blade l by screws 3 extending through liirs 3" on the table 3 and screwing into suitable holes in the blade l in such position that when the shears are closed the presser plate 2 will be parallel to the table 3.

Toggle arms 4 are pivotally connected with the blades 1 and l, respeotivel and with each other, and with the looper ar 5; in suoli manner that the opening and closing of the shears will impart a reci rocating movement to the looper bar. T e looper bar 5 slides freely in a stationary ide 5 on the under side of the table 3. he looper plate G is secured on the bar 5.

A fixed aw 7 is secured on the looper plate. 6 by rivets 7d or equivalent securing devices. A movable jaw 7 is pivotally connected with the plate 6. The jaws 7 and 7 have shoulders 7" which prevent the thread from slip- )ing too far rearward on the jaws while the loo oopor is moving forward during the making of the stitch.

A spring 8 is mounted on the plate 6 and the free end of the s )ring acts on a lug 7 on the jaw 7 to normally hohl the oint of the 106 movable 'aw 7 in contact with tilie point of the fixed jaw 7; but yields to icrmit the jaw 7 to move sufficiently for the needle i) to pass between the jaws during the rearward movement of the looper.

A lplate 10 secured in a horizontal position on t e blade 1El at right angles'to the blade', serves as a spool support and a needle support. The spool 11 carrying the thread used in basting turns on a hxed vertical stem 10* on the plate 10. The plate 10 has an inte al circular, tapering and screw threade split stud 10b having a central o ening 10 in which the shank of the nee( le 9 fits. A nut 12 screws onto the stud 10b and presses together the members of the stud to old the needle firmly in any position in which it may be set. A channeled block 13 secured on the blade l serves to guide the needle. The opening of the shears during the operation of cutting causes the toggle arms 4 to move the looper forward into the position shown in Fig. 10 and also causes the needle to assume the raised position shown in the same view.

During the operation of cutting the shears move forward on the fabric and the length of the stitch depends upon the extent of the forward movement of the shears at each step of the cutting. U on the partial closing of the shears the need e will descend, the position of the needle at different stages of its descent bein shown in Figs. 11, 12 and 13. During the escent of the needle the point of the needle passes downward between the jaws 7 and 7 as shown in Figs. 5 and 12. During the latter part of the downward movement o the needle, incident to the closing of the shears, the toggle arms 4 act to move the looper rearward, away from the needle, into the position shown in Figl.l 13. The thread Y carried in the eye of t e needle at this stage of the o ration extends downward through the fa ries and lies alongside the needle as shown in Fig. 13. Upon again openin f the shears the needle will begin to rise an will cause the thread to loop as shown in Fig. 14

and further openin(r of the shears will cause the looper .to move forward into the loop, be-

tween thel needle and the thread, and the shoulders 7b engaging with the thread will push the loop forward as indicated in Fig. l5, the position of the loop being such that when the needle next descends it will pass downward through the loop and between the jaws 7 and 7", thus forming one stitch; and this` will be re ieated and successive stitches will be formed, so long as the apparatus continues in operation.

ln practice the fabrics X will be placed face to face and the shears will be o )erated to cnt them to the desired pattern ami the operating of the shears will causo the needle and looper to coperatc to baste the fabrics as already described.

llaving fully described my invention, what I claim as new, and desire to secure by .Letters Patent, is:

A combined cutter and baster comprising shear-memberspivotally connected with each other and having studs, a needle mounted on one of the shear-members, a presser plate mounted on the same shearmember and adapted to permit the passage of the cuttingled re of the complemental shear-member, a

ta le fixed on the complemental shear-member, a looper mounted on the complemental shear-member and adapted to cooperate with the needle, arms pivotally connected with each other and with the studs on the shearmembers, and a rod connecting the looper with said arms.

In witness whereof I have hereunto signed my name, at Athens, Illinois, this 10th day oi' November 1906.

SARAH E. CANTRALL.
